For transmissions- the 240sx takes GL-4 fluid, which is now hard to find, at least for me locally...everthing was GL-5.

The problem is that most fliuds are now GL-5 rated, which is not friently with Brass Synchro's in the tranny. I used AMSOIL Synthetic tranny fluid. Great, but sometimes a little difficult going into gear around freezing temperatures. No issues above 50 degrees.

Others use Redline Mt-90 and some use GM Syncromesh (or mix in some). I also recommend OEM nissan fluid to get it and never have issues...

I'm going to put XXX in the factory VLSD, it's sealed and fluid has no effect on performace. So something synthetic adn close to factory specs 80w-90.

I will change fluid every 1.5 years for my daily which see's limited track use.
